I Specification of Letters Patent.

Patented Oct. 30, 1906.

Application filed May 7, 1906. Serial No. 315.575.

To all whom it may concern- I Be it known that I, JOHN ANDERSON, a citizen of the United States, residing at Portland, in the county of Middlesex and State of Connecticut, have invented a new and useful Improvement in Wrenches; and I do hereby declare the following, when taken in connection with the accompanying drawings and the letters of reference marked thereon, to be a full, clear, and exact description of the same, and which said drawings constitute part of this specification, and represent, in-

Figure 1, aside View of a wrench constructed in accordance with my invention; Fig. 2, a similar view with one side of the handle and link portion removed; Fig. 3, a sectional View on line a b of Fig. 1 Fig. 4-, an edge view of the jaws detached.

This invention relates to an improvement in Wrenches, the object being a simple construction and arrangement of parts permitting a convenient adjustment of the jaws with relation to each other and at various angles with relation to the handle, and the invention consists in the construction and arran ement of parts, as will be hereinafter described, and particularly recited in the claims.

In carrying out my invention I employ a jaw-block 2, having formed with it a fixed jaw 3 and slotted to receive the rack portion 5 of a movable jaw 6, one of the walls of the slot being formed with a longitudinal rib entering a corresponding roove 8, formed in one side of the rack, who at its under edge has teeth 9, which are engaged by a worm-' nut 10, mounted upon a pin 11, the nut being exposed on opposite sides by a clearanceopening 12, formed for that purpose in the block 2, so that by the turning of the nut 10 the movable jaw- 6 may be moved toward or from the fixed 'aw 3. The block2is provided at opposite sides with integral studs 13 and 14, and one side is thereby pivotally connected to the upper end of the handle portion 15. This handle portion is formed from a strip of metal doubled into substantially than at its upper end to form a gripping portion 16. Located within the handle and secured thereto by rivets 17 is a block 18,

Preferably and as herein shown the outer l same way as is the handle portion 15. Pivoted to the lower end of the link 21 is a yoke 25, which surrounds the handle portion and contains a flat spring 26, which rides in the groove 20 and holds the-dog 22 in engagement with the block 18, yet yields to permit the yoke to be pressed against the handle por-- tion, so as to throw the dog out of engagement with the block, allowing the link to be moved, and so as to turn'the jaw-block at various angles with relation to the handle. This construction permits the jaws to be separated or moved toward each other for various sizes of'bolts, and by shifting the engagement of the dog with the block the 'aws may be turned at various angles to the andle, as may be required for convenience and operation.

Iclain1 1. A wrench comprising a jaw-block having a fixed jaw thereon, a movable jaw sliding in said block, and means for adjusting it toward and from the fixed jaw, a handle portion pivoted to one side of said block and containing a notched block, a link pivoted to the opposite side of said jaw-block and containing a do at its lower end for engagement with the andle portion, and means for holding them in such engagement, substantially as described.

2. A wrench comprising a jaw-block, said block having a fixed jaw and integrallyformed studs at opposite sides, said block also slotted, a movable jaw arranged in said slot, and means for moving it toward and from the fixed jaw, a handle portion connected with the studs at one side of said block, and a link member connected with the studs at opposite sides of said block, said handle member including a notched block, and the link member a toothed dog to engage therewith, and means for holding said dog and block in engagement, substantially as described.

3. A wrench comprising a jaw-block having a fixed jaw thereon, a movable jaw sliding in said block and means for adjusting it toward and from the fixed jaw, a handle portion pivoted to one side of said block, said handle portion formed from sheet metal bent into U shape and formed at its outer edge with a longitudinal groove, a block located between the sides of said handle and having its edge notched, a link also connected with said jawblock and formed from sheet metal, said link containing a dog adapted to engage with said notched block, and means for holdin said dog in engagement with the notched block, substantially as described.

In testimony whereof I have signed this 15 specification in the presence of two subscribing witnesses.

JOHN ANDERSON.
